The Boston Globe has asked five Democrats to explain what’s next for the party. As with so many of these symposia, my favorite entry is the one that gives the worst advice. In this case, it’s from Rick Perlstein, a Village Voice writer. He believes Democrats should declare war on Wal-Mart: “When heartland Americans are asked what they think is going wrong with America, ‘Wal-Mart’ is one of the first words out of their mouths.” Why? Because there aren’t enough of them? Because they wish the aisles were cleaned up a little better? No, because Wal-Mart is a corporate predator that breaks anti-discrimination laws and destroy jobs. Hillary Clinton, Perlstein reminds us, “is a former member of the board of directors of Wal-Mart. She should not be able to get within spitting distance of a Democratic presidential nomination until she explains, if not apologizes for, her service on it.”
